Hi Javier; Welcome to Permies.
The short
answer to your question is yes, it could be done.
There are 2 styles of
rocket stove. A traditional J tube which requires more attention or a new style Batch box ,hotter burning , harder to build, but once lit it is maintenance free for the next 1.25 hrs.
I do not know the climate where your factory is located. If it is a cold place then your outside firebox might need a small room to be located in.
I highly recommend locating a copy of "The
Rocket Mass Heater Builders Guide" written by Ernie & Erica Wisner accomplished master builders with over a 1000 builds.
